The capacitive liquid level sensor is a metal rod pierced into the liquid container. From this equation, the measured capacitive is proportional to the length submerged into water, as the approximate capacitance per length of track for a coplanar sensor remains constant. Walker, Charles S. Capacitance, Inductance and Crosstalk Analysis, Artech House, 1990, ISBN: 978-0890063927. It is widely used for position detection in various high temperature, high pressure, strong acid and strong alkali, and various powder and particle environments in petroleum, chemical, metallurgical, light industry, coal, cement, grain, and other industries. The external host can then read the final result via the serial interface. The most obvious difference is that one uses electromagnetic waves and the other uses ultrasonic waves. The material of the storage tank can be various metals, non-metals or non-foamed plastics. A simple technique for monitoring liquid levels is to immerse a parallel-plate capacitor in the liquid, as shown in Figure 3. Capacitance-to-Digital Converter Facilitates Level Sensing in Diagnostic Systems Analog Dialogue, Volume 48, Number 2, 2014.
